This manual describes the operation of the Vaisala HUMICAP® humidity and temperature measurement instrument and HMI41 probes.
The HMI41 indicator displays relative humidity, temperature and dew‑point, and can also show absolute humidity, wet‑bulb temperature or mixing ratio. It works with a range of probes (HMP42, HMP44, HMP45, HMP46) that are automatically recognised when the instrument label contains an ID number.
The device includes an auto‑power‑off feature, manual or automatic data collection, adjustable measurement intervals and periods, and optional serial interface for PC transfer. Batteries are four AA cells, and the instrument can be calibrated with a supplied adapter cable. This manual is written in Japanese.
